I have some pretty good forearms at least in comparison to my bi's and tri's
I do like it, but as a result I really struggle to activate my biceps during curls... I get a massive pump in my brachialis and forearms and don't really get a deep contraction or pump in my actual biceps. It's probably the reason my biceps have always lagged.
I dont think I'd trade them for better biceps, though. I have a friend who is the other way around... big bi's and small forearms but I personally dont think the small forearms is a good look.
